Overview​

This is an intermediate release focusing on infrastructure improvements and bug fixes. The release addresses critical issues with OpenTelemetry configuration, health check reliability, and container image distribution.

🔧 Infrastructure Improvements​

Container Image Distribution​

The vNext Init component has been migrated from local Docker builds to centralized image registry distribution.

Changes:

  • Removed local Dockerfile.vnext-core-init
  • Now using pre-built image: ghcr.io/burgan-tech/vnext/init:${VNEXT_INIT_VERSION}
  • Added VNEXT_INIT_VERSION=0.0.13 environment variable
  • Improved deployment consistency across environments
  • Added npm cache volume for better performance

Benefits:

  • Faster deployment times
  • Consistent image versions across environments
  • Reduced build complexity
  • Better resource utilization

OpenTelemetry gRPC Protocol Fix​

Fixed OpenTelemetry configuration to use proper gRPC protocol instead of HTTP.

Configuration Changes:

# Before (HTTP/Protobuf - causing issues)
Telemetry__Otlp__Endpoint=http://otel-collector:4318
Telemetry__Otlp__Protocol=http/protobuf

# After (gRPC - stable)
OTEL_EXPORTER_OTLP_ENDPOINT=http://otel-collector:4317
OTEL_EXPORTER_OTLP_PROTOCOL=grpc

Impact:

  • Resolved telemetry data transmission issues
  • Improved observability reliability
  • Better performance with gRPC protocol
  • Consistent with OpenTelemetry best practices

Health Check Improvements​

Enhanced health check reliability and service startup coordination.

Makefile Enhancements:

  • Added 3-second delay before checking VNext Execution service
  • Improved service coordination during startup
  • Better error handling in health check commands
  • Enhanced user feedback during service verification

Docker Compose Health Checks:

  • Fixed health check URLs to use container names instead of localhost
  • vnext-app: http://vnext-app:5000/health
  • vnext-execution-app: http://vnext-execution-app:5000/health
  • Improved container-to-container communication reliability

🐛 Bug Fixes​

Service Communication​

  • Fixed health check endpoints to use proper container networking
  • Resolved intermittent health check failures
  • Improved service discovery reliability

Container Orchestration​

  • Enhanced service startup sequence
  • Better dependency management between services
  • Improved container restart behavior

Telemetry Stability​

  • Resolved OpenTelemetry connection issues
  • Fixed trace data export problems
  • Improved monitoring reliability

📋 Configuration Updates​

Environment Variables​

New and updated environment variables:

# New Init Image Version
VNEXT_INIT_VERSION=0.0.13

# Updated OpenTelemetry Configuration
OTEL_EXPORTER_OTLP_ENDPOINT=http://otel-collector:4317
OTEL_EXPORTER_OTLP_PROTOCOL=grpc

Docker Compose​

  • Added npm cache volume for improved performance
  • Updated health check configurations
  • Enhanced service networking

🚀 Deployment Notes​
